Review on Alumaloy 20 Rods: USA Made, As Seen on TV, 1/8" x 18" Aluminum Welding Rods for Simple Welding, Brazing, and Repair by Michael Murphy

The reviews I've read on here have ranged from terrible to great so I was a bit unsure about these things but they work great! I would call that brazing, not soldering or welding, and if you've ever steamed copper tubing you know the technique. Heat the workpiece, from time to time tear off the flame and use a chopstick to check if it is hot enough. Never bring a flame to the rod, use the heat of the work piece to melt it and it will flow like solder. I use the other end of the rod to shake off the excess for a cleaner look. I am satisfied with the product.
